Abstract

Un ensemble optique (10) de collecte de rayonnement possède un miroir convexe (1), un miroir concave (2) à ouverture centrale (O) et un hublot (3), disposés pour que du rayonnement traverse l’ouverture du miroir concave, soit réfléchi par le miroir convexe puis par le miroir concave, et traverse ensuite le hublot. L’ensemble optique est approprié pour être utilisé dans un dispositif autodirecteur de guidage d’engin autopropulsé, en évitant qu’un composant optique d’entrée d’un tel dispositif soit dégradé et rendu inopérant par abrasion lorsqu’il est exposé à un flux d’air à vitesse élevée qui contient des particules denses.Figure d’abrégé : Figure 1A radiation collection optical assembly (10) has a convex mirror (1), a concave mirror (2) with a central aperture (O) and a window (3), arranged so that radiation passes through the aperture of the concave mirror, is reflected by the convex mirror then by the concave mirror, and then passes through the porthole. The optical assembly is suitable for use in a self-propelled vehicle homing guidance device, avoiding that an optical input component of such a device is degraded and rendered inoperative by abrasion when exposed to a flow of high-velocity air that contains dense particles.Abstract figure: Figure 1
